Definitions

  • the present invention relates to a communication control method and a communication system of a base station and a mobile station in a communication system. More specifically, it relates to a communication control method in CDMA communication system which is suitable for communication for emergency situation when compared with normal communication, and to a communication system including a base station and mobile stations.
  • the near-far problem is always a problem in CDMA (Code Division Multiple Access) system. If mobile stations transmit at the same power, the radio wave from mobile stations far from a base station is weak at the base station and the radio wave from mobile stations near the base station is strong at the base station, which causes the problem. This has not been a problem in the Frequency Division Multiple Access (hereafter described as FDMA) and the Time Division Multiple Access (hereafter described as TDMA) being conventional multiplexing communication systems.

  • TDMA Time Division Multiple Access
  • each mobile station uses a different frequency. Therefore, even if strength of the radio wave from a far mobile station and strength of the radio wave from a close mobile station are different, the base station can distinguish them according to frequencies.
  • TDMA each mobile station uses a different time slot. Therefore, the radio wave from a far mobile station and the radio wave from a close mobile station do not simultaneously come to the base station. Accordingly, even if strength of the radio wave from the distant mobile station and strength of the radio wave from the close mobile station are different, the base station can distinguish them according to time slots.

This is called power control.

  • the noise needs to be transmitted at the field strength strong enough to interfere with communication between the base station 100 and the other mobile stations.
  • a sign indicating communication for emergency situation or terminal information of the mobile station 200a as a flag indicating to be communication for emergency situation, which should be included in the communication system according to Embodiment 2, not in the similar type of the present Embodiment.
  • the base station 100 transmits suppression signals of field strength to all the mobile stations for instructing to reduce outputs (field strength) (S13).
  • the output reduction instruction mobile stations other than the mobile station 200a reduce field strength in response to the suppression signals, so that signals from the other mobile stations stop reaching the base station 100 and the communication stops (S14).
  • the mobile station 200a ignores the suppression signals of field strength from the base station 100, and transmits not an interference wave (noise), but the contents of the communication for emergency situation to the base station 100 at the maximum output permitted in an emergency (S15). It is assumed that the base station continues to output the output reduction instructions. By detecting that links with the other mobile stations are disconnected, the base station 100 recognizes that the request of communication for emergency situation is sent from the mobile station 200a (S14, S15).
  • the mobile station 200a can obtain an output relatively larger than the other mobile stations until the other mobile stations return outputs to the original ones. Therefore, even if the base station 100 does not send output reduction instructions, the base station 100 can recognize that the request of communication for emergency situation is sent from the mobile station 200a.
  • the channel is established like Embodiment 1, and the communication for emergency situation is performed based on the normal communication procedure.
  • the mobile station 200a requesting the communication for emergency situation can inform the base station 100 that the mobile station 200a is requesting to establish channel for emergency situation, by outputting only the noise to interfere with normal communication between other mobile stations and the base station 100, without including the contents notifying the emergency in the signal.
  • the communication systems according to all the Embodiments stated above can also be realized by the internal structure of the base station 100 and the mobile station 200 as shown in Fig. 8.
  • the output control part 202 and the emergency communication call part 206 do not exist in the mobile station 200, and instead of them, an emergency communication management part 300 is needed between the mobile station 200 and the base station 100.
  • the emergency communication management part 300 includes an emergency communication call part 302 and an amplifier 304.
  • the emergency communication call part 302 requests to initiate a call of communication for emergency situation, and has the same function as the emergency communication call part 206 in the internal structure of the mobile station 200 of Fig. 3.
  • the amplifier 304 In response to the call request of the communication for emergency situation sent from the emergency communication call part 302, the amplifier 304 amplifies the power of the signal (the call signal of communication for emergency situation) transmitted from the mobile station side transmission part 208 to be field strength strong enough to interfere with communication between other mobile stations and the base station 100.
  • the base station side reception part 108 receives the call signal of communication for emergency situation amplified by the emergency communication management part 300. Subsequent operations are the same as those in Embodiment mentioned above. Compared with the base station 100 shown in Fig. 3, the output control part 102 is unnecessary for the base station 100 shown in Fig. 8.
  • the internal structure of the mobile station 200 can be simplified by structuring the communication system as shown in Fig. 8. Since users' requirements of reduction in weight and downsizing of volume for the mobile station 200 are high, such users' requirements can be satisfied with the communication system illustrated in Fig. 8.
  • CDMA is a communication method especially suitable for the invention described in the Embodiments.
  • the present invention is not limited to CDMA, and is applicable to any communication method as long as the near-far problem occurs in the communication method. While there are several methods in CDMA, it is preferable for the present invention to use the direct spread system used by many systems.
  • the present invention can be utilized. Also, even if a system using the power control system or a method of using an artificial satellite as a base station and stations on the earth (the airspace also being included) as mobile stations is adopted, the present invention can be utilized.
  • the field strength which is output by the mobile station 200 and is strong enough to interfere with communication between the other mobile stations and the base station 100 in an emergency may be about one hundred times the field strength used for normal communication. Specifically, it may be about 20dB. In the case of distress communication, the field strength used for the communication for emergency situation is assumed to be about 10KW, whereas the field strength used for normal communication by the mobile station 200 is about 100W.
  • an emergency button is provided in the interface of the mobile station 200, a function to transmit a signal storing data indicating an emergency is linked to the emergency button, and the communication for emergency situation is called by a user's pushing the emergency button.
  • the communication systems according to all the Embodiments can be realized with a small revision of the communication system conventionally used. Therefore, when applying the communication system according to the present invention to communication using CDMA system, it is possible to preferentially deal with communication for emergency situation using a comparatively simple protocol.
  • the communication control method according to the present invention is simple, the following can be realized: easy implementation because of the simplicity, cost reduction, and high reliability in terms of the number of parts being small.
  • Fig. 9 shows a computer basic structure of the base station 100 and the mobile station 200.
  • a CPU 40 which executes programs is connected with a monitor 41, a keyboard 42, a mouse 43, a communication port 44, a magnetic disk drive 46, etc. through a bus 38.
  • An OS 47, a program group 49, and a file group 50 are stored in the magnetic disk drive 46.
  • the form in which the program group 49 and the file group 50 are united to be an object-oriented program group 49 can be considered as one of the Embodiments.
  • each part structuring the base station 100 and the mobile station 200 is implemented with a program
  • the present invention is executed, for instance, by storing a program in which operations to be executed by the output control part 202 are coded and a program in which operations to be executed by the emergency communication call part 206 and so on are coded in the magnetic disk drive 46 as the program group 49, and by executing each program stored in the magnetic disk drive 46 with the CPU 40 and the OS47.
  • the base station 100 and the mobile station 200 use the function of the communication port 44, and radio communication is performed.
  • each operation of each structure element relates to each other, and taking the relation of the operations stated above into consideration, the operation of each structure element can be replaced as a series of operations. And such replacement enables them to be Embodiments of a method invention. Moreover, replacement of the operation of each structure element by processing of each structure element enables them to be Embodiments of a program. Moreover, by storing the program in a computer-readable recording medium in which a program is stored, they can be Embodiments of a computer-readable recording medium stored in a program.
  • the Embodiment of the program for controlling mobile station side communication can be an Embodiment of a computer-readable recording medium storing a program for controlling mobile station side communication, wherein the computer-readable recording medium stores the program, to be executed by a computer, for controlling mobile station side communication, which communicates with a base station, including:
  • the Embodiment of the program for controlling base station side communication can be an Embodiment of a computer-readable recording medium storing a program for controlling base station side communication, wherein the computer-readable recording medium stores the program, to be executed by a computer, for controlling base station side communication, which communicates with a plurality of mobile stations, including:
  • Embodiment of a program and Embodiment of a computer-readable recording medium stored in a program can be structured by a program the entirety of which is operable in a computer.
  • Each processing in Embodiment of a program and Embodiment of computer-readable recording medium storing a program can be executed by a program, which is stored in a recording device, loaded from the recording device into a central processing unit (CPU), and executed by the central processing unit.
